General properties

Stable at high temperature (up to 200°C / 392°F or 400°C / 752°F depending on the product) and Chemical (water and oxygen)

Hydrophobic or Hydrophilic

Good conductors (electrolytes)

Broad electrochemical range

The physico chemical properties of ionic liquids depend on the type and the size of the two ions forming them. For example, ionic liquids containing chloride, bromide or trifluoroacetate anions are highly water soluble (hydrophilic). Conversely, when they are associated with an anion such as hexafluorophosphate or bis(trifluoromethanesulfonyl)imide, water solubility is very limited (hydrophobic), forming two liquid phases.

Advantages

Safer for the environment and for users (non flammable and non volatile)
